Some of the compounds of the formula I have one or more asymmetric carbon atoms or stereoisomers on double bonds. Enantiomers or diastereomers may therefore occur. The invention embraces both the pure isomers and mixtures thereof. The mixtures of diastereomers can be separated into the components by customary methods, for example by selective crystallization from appropriate solvents or by chromatography. Racemates can be resolved into the enantiomers by customary methods, for example by forming a salt with an optically active acid, separating the diastereomeric salts and liberating the pure enantiomers by means of a base.

The invention additionally relates to a process for the preparation of compounds of the formula I, which comprises reacting a compound of the formula (II) ##STR23## where B is CH or N and R¹, R², R³, X, Y and Z are each as defined under formula I, with an electrophil of the formula (III), ##STR24## where R⁴, R⁵, R⁶ and E are each as defined under formula I and Lg is a leaving group, for example halogen, alkylthio, alkanesulfonyloxy or arylsulfonyloxy, alkylsulfonyl or arylsulfonyl, preferably halogen, if appropriate with the addition of salts such as, for example, AgBF₄, AgNO₃ or Nal, and, if appropriate, replacing the anion of compounds obtained in this manner with other anions similarly to known methods for example Liebigs Ann. Chem. 1978, 1937; Methoden der Org. Chemie/Houben-Weyl (D. Klamann, Ed.), 4th edition, Vol. E16a, Part 2, p. 1008 ff, Thieme, Stuttgart 1990!.

The invention also relates to compositions, especially insecticidal and acaricidal compositions, which comprise the compounds of the formula I in addition to suitable formulation auxiliaries.

The compositions according to the invention comprise the active substances of the formula I in general in a proportion of from 1 to 95% by weight.

They can be formulated in various ways depending on the biological and/or chemicophysical parameters which prevail. Possible formulations which are suitable are therefore:

wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions, sprayable solutions, oil- or water-based dispersions (SC), suspoemulsions (SE), dusts (DP), seed-dressing products, granules in the form of microgranules, spray granules, coated granules and adsorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits.

These individual types of formulation are known in principle and are described, for example, in: Winnacker-Kuchler, "Chemische Technologie", Volume 7, C. Hauser Verlag Munich, 4th ed. 1986; van Falkenberg, "Pesticides Formulations", Marcel Dekker N.Y., 2nd ed. 1972-73; K. Martens, "Spray Drying Handbook", 3rd ed. 1979, G. Goodwin Ltd. London.

The formulation auxiliaries required, such as inert materials, surfactants, solvents and other additives, are likewise known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd ed., Darland Books, Caldwell N.J.; H. v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd ed., J. Wiley & Sons, N.Y.; Marsden, "Solvents Guide", 2nd ed., Interscience, N.Y. 1950; McCutcheon's, "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflafchenaktive Athylenoxidaddukte", Wiss.Verlagsgesell., Stuttgart 1967; Winnacker-Kuchler, "Chemische Technologie", Volume 7, C. Hauser Verlag Munich, 4th ed. 1986.

Based on these formulations, it is also possible to produce combinations with other pesticidally active substances, fertilizers and/or growth regulators, for example in the form of a readymix or a tank mix. Wettable powders are preparations, uniformly dispersible in water, which contain, beside the active substance and in addition to a diluent or inert material, wetting agents, for example polyoxethylated alkylphenols, polyoxethylated fatty alcohols, alkyl- or alkylphenolsulfonates, and dispersing agents, for example sodium ligninsulfonate or sodium 2,2'-dinaphthylmethane-6,6'-disulfonate.

Emulsifiable concentrates are prepared by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or higher-boiling aromatics or hydrocarbons, with addition of one or more emulsifiers. As emulsifiers, the following can be used, for example: calcium salts of alkylaryl-sulfonates, such as Ca dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or poly-oxethylene sorbitol esters.

Dusting agents are obtained by grinding the active substance with finely divided solid substances, for example talc, natural clays such as kaolin, bentonite, pyrophillite or diatomaceous earth. Granules can be prepared either by atomizing the active substance onto adsorptive, granulated inert material or by applying active substance concentrates onto the surface of carrier materials such as sand or kaolinites, or of granulated inert material, by means of adhesives, for example poly-vinyl alcohol or sodium polyacrylate, or alternatively mineral oils. Suitable active substances can also be granulated in the fashion conventional for the preparation of fertilizer granules, if desired as a mixture with fertilizers.

In wettable powders, the concentration of active substance is, for example, from approximately 10 to 90% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the concentration of active substance may be from approximately 5 to 80% by weight. Formulations in dust form comprise in most cases from 5 to 20% by weight of active substance, sprayable solutions from about 2 to 20% by weight. In the case of granules, the content of active substance depends partly on whether the active compound is in liquid or solid form and on which granulation auxiliaries, fillers, etc. are being used.

In addition, the abovementioned formulations of active substance comprise, if appropriate, the adhesives, wetting agents, dispersants, emulsifiers, penetrants, solvents, fillers or carriers which are customary in each case.

The concentrates, which are in the commercially customary form, are if appropriate diluted in the customary manner for their use, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and some microgranules. Dust and granule preparations, and also sprayable solutions, are normally not diluted any further with other inert substances before being used.

The application rate required varies with the external conditions, such as temperature and humidity among others. It can fluctuate within wide limits, for example between 0.0005 and 10.0 kg/ha or more of active substance, but is preferably between 0.001 and 5 kg/ha.

The active substances according to the invention may be present in their commercially customary formulations, and in the application forms prepared from these formulations, as mixtures with other active substances, such as insecticides, attractants, sterilants, acaricides, nematicides, fungicides, growth regulators or herbicides.

The pesticides include, for example, phosphates, carbamates, carboxylates, formamidines, tin compounds and substances produced by microorganisms, inter alia.

The active substance content of the use forms prepared from the commercially customary formulations can be from 0.00000001 to 95% by weight of active substance, preferably between 0.00001 and 1% by weight.

Application is effected in a conventional fashion, matched to the use forms.

The active substances according to the invention are also suitable for controlling ecto- and endoparasites in the veterinary sector or in the sector of animal husbandry.

The active substances according to the invention are in this case administered in a known fashion, such as by oral administration in the form of, for example, tablets, capsules, potions or granules, by dermal administration in the form of, for example, dipping, spraying, pouring-on and spotting-on and powdering, and also by parenteral administration in the form of, for example, injection.

The novel compounds, according to the invention, of the formula I can accordingly also be employed particularly advantageously in livestock husbandry (for example cattle, sheep, pigs and poultry such as chickens, geese etc.). In a preferred embodiment of the invention, the novel compounds, if appropriate in suitable formulations (cf. above) and if appropriate with the drinking water or feed, are administered orally to the animals. Since excretion in the droppings occurs in an effective fashion, the development of insects in the animal droppings can be prevented very simply in this fashion. The dosages and formulations suitable in each case are particularly dependent on the type and stage of development of the productive animals and also on the degree of infestation, and can easily be determined and fixed by conventional methods. In the case of cattle, the novel compounds can be employed, for example, in dosages of 0.01 to 1 mg/kg of body weight.

The compounds of the formula I according to the invention also have an outstanding fungicidal action. Fungal pathogens which have already penetrated the plant tissue can be successfully subjected to curative control. This is particularly important and advantageous in the case of those fungal diseases which can no longer be controlled effectively with the otherwise customary fungicides when infection has taken place already. The spectrum of action of the claimed compounds embraces various economically important phytopathogenic fungi, for example Plasmopara viticola, Phytophthora infestans, Erysiphe graminis, Pyricularia oryzae, Pyrenophora teres, Leptosphaeria nodorum, Pellicularia sasakii and Puccinia recondite.

In addition, the compounds according to the invention are also suitable for use in technical fields, for example as wood preservatives, as preservatives in paints, in cooling lubricants for metalworking, or as preservatives in drilling and cutting oils.

The active substances according to the invention in their commercially customary formulations can be employed either alone or in combination with other fungicides known from the literature.

Examples of fungicides which are known from the literature and which can be combined, in accordance with the invention, with the compounds of the formula I are the following products:

The abovementioned components for combinations are known active substances of which many are described in Ch. R. Worthing, S. B. Walker, The Pesticide Manual, 7th edition (1983), British Crop Protection Council. The active substance content of the use forms prepared from commercially customary formulations can vary within wide limits, and the concentration of active substance in the use forms can be from 0.0001 up to 95% by weight of active substance, preferably between 0.0001 and 1% by weight. The formulations are applied in a customary manner adapted to suit the use forms.

The examples which follow illustrate the invention without limiting it thereto.

A. FORMULATION EXAMPLES

a) A dusting agent is obtained by mixing 10 parts by weight of active substance and 90 parts by weight of talc as inert material and comminuting in a hammer mill.

b) A wettable powder which is easily dispersible in water is obtained by mixing 25 parts by weight of active substance, 65 parts by weight of kaolin-containing quartz as inert material, 10 parts by weight of potassium ligninsulfonate and 1 part by weight of sodium oleoylmethyltaurinate as wetting and dispersing agent, and grinding in a pinned disk mill.

c) A dispersion concentrate which is easily dispersible in water is prepared by mixing 40 parts by weight of active substance with 7 parts by weight of a sulfosuccinic monoester, 2 parts by weight of a sodium ligninsulfonate and 51 parts by weight of water and grinding in a ball mill to a fineness of below 5 microns.

d) An emulsifiable concentrate can be prepared from 15 parts by weight of active substance, 75 parts by weight of cyclohexane as solvent and 10 parts by weight of ethoxylated nonylphenol (10 EO) as emulsifier.

e) Granules can be prepared from 2 to 15 parts by weight of active substance and an inert granule carrier material such as attapulgite, granulated pumice and/or quartz sand. It is advantageous to use a suspension of the wettable powder of Example b) with a solids content of 30% which is sprayed onto the surface of attapulgite granules which are then dried and intimately mixed. The proportion by weight of the wettable powder in this case is about 5% and that of the inert carrier material is about 95% of the finished granules.

B. PREPARATION EXAMPLES Example I ##STR25## 4-(2-Decylamino)-5-methoxy-6-methoxymethyl-1-phenacylpyrimidinium bromide

A mixture of 1.5 g (4.84 mmol) of 2-decylamino-5-methoxy-6-methoxymethylpyrimidine (DE-A4 116 089) and 0.96 g (4.84 mmol) of phenacyl bromide in 50 ml of ethanol was heated under reflux for 8 hours. After cooling, the solvent was removed under reduced pressure and the oily residue was stirred with petroleum ether. The resulting crystal slurry was filtered off with suction and the product was stirred in hot petroleum ether for another 5 minutes. Filtration with suction gave 1.15 g (61% of theory) of a yellow solid. mp. 118° C.

Example II ##STR26## 1-Benzoyloxymethyl-5-bromo-6-ethyl-4- 2-(2,4-dimethylphenoxy)-propylamino!pyrimidinium iodide

0.3 g (8.2 mmol) of 5-bromo-6-ethyl-4- 2-(2,4-dimethylphenoxy)-propylamino!pyrimidine (according to EP-A-57 440), 0.17 g (9.8 mmol) of chloromethyl benzoate and 0.12 g (8.2 mmol) of sodium iodide in 25 ml of acetone were heated under reflux for 8 hours. After cooling, the precipitated sodium chloride was filtered off and the filtrate was concentrated. The residue was taken up in dichloromethane and washed by stirring with water. The organic phase was dried and concentrated. The residue was digested with ethyl acetate. Filtration with suction gave 0.97 g (53.3% of theory) of light-yellow crystals. mp.: 159-161° C.
